PHP filesize() | Get Size of File
The PHP filesize() function returns the size of specified file in bytes. For example:
<?php echo filesize("codescracker.txt"); ?>
The output produced by above PHP example on filesize() function is:
And here is the snapshot of the file codescracker.txt, used in above example:
PHP filesize() Syntax
The syntax of filesize() function in PHP, is:
filesize(fileName)
PHP Get File Size in KB using filesize()
<?php $myfile = "codescracker.txt"; $x = filesize($myfile); $x = $x/1024; echo "<p>Size of File, $myfile is $x KB</p>"; ?>
The output produced by above PHP example, to find and print the size of a file in KB, is:
If you want to remove all the digits after the decimal, then put (int) before the size, in similar way as done in following program:
<?php $myfile = "favicon.ico"; $x = filesize($myfile); $x = (int)($x/1024); echo "<p>Size = $x KB</p>"; ?>
Now the output should be Size = 30 KB, because the file favicon.ico is of 30 KB. I've not used codescracker.txt file in above example, as the size of that file is 46 bytes, that will give 0 KB as output.
PHP Get File Size in MB using filesize()
<?php $myfile = "C:/xampp/xampp-control.exe"; $x = filesize($myfile); $x = (int)($x/1024/1024); echo "<p>Size = $x MB</p>"; ?>
The output produced by this PHP example, that prints the size of xampp-control.exe file available in C:/xampp/ directory, is shown in the snapshot given below:
And here is the snapshot of the file along with directory used in above example:
PHP Get File Size in GB using filesize()
<?php $myfile = "F:/sw/os/windows64.iso"; $x = filesize($myfile); $x = (int)($x/1024/1024/1024); echo "<p>Size = $x GB</p>"; ?>
Since the size of file windows64.iso is 5.1GB, therefore after removing .1, you will get Size = 5 GB as output.
